Question

If angle of a triangle are (x-10°), (2x+10°) and 6 x than value of x is


Plz answer fast....​

Answer 1

Answer:

20

Step-by-step explanation:

by anglesum property of triangle

sum of angles of triangle =180*

(x-10)+(2x+10)+6x=180

x+2x+6x-10+10=180

9x=180

x=180/9=20

Answer 2

Given ; angle of a triangle are (x-10°), (2x+10°) and 6 x

To Find ; The value of x

Solution ; Angle of a triangle are (x-10°), (2x+10°) and 6 x

Angle sum of a triangle is 360°

x-10° + 2x +10° +6x = 360

9x= 360°

x =40

Hence the four angles are 30° ,90° and 240°
